(Cl. 206-65) The present invention relates to an improved wood pole treating bandage for supporting and enclosing a wood preservative-protective grease product to be applied to the top of a line pole.

The invention pertains to the method of treating wood with preservative-protective material after the wood is put in use, and particularly to treating wood posts or poles such as electrical line poles. The poles are treated by applying wood preservative to the top end where it can penetrate the end grain of the wood. This extends the useful life of poles already in the line by adding extra years of service and the application of preservative will add extra years to the life of the poles. Poles which were poorly treated upon installation or were not treated, or were treated with inferior preservatives can be treated with materials of an improved character. The preservative material is a grease or a grease-like composition which is carried on a bandage forming a protective enclosure during storage and handling and forming an applicator and carrier for applying to the pole. The bandage is particularly adapted to being suspended on an applicator tool which is elevated to the top of a pole for applying the bandage.

A feature of the invention i the provision of a bandage construction having a supporting layer of water soluble film tor dissolving when exposed to precipitation with a slab of wood preservative-protective grease material on the layer, and with a layer of porous material such as crinoline over the grease material and a further removable protective layer of water soluble film secured by a continuous seam at its edges to the supporting layer and positioned over the porous layer and readily separable therefrom for removal in order that the grease material may be placed over the top of a pole with the porous material facing downwardly.

A further feature of the invention is the provision of an improved method and machine for the construction of the wood pole treating bandage, by supporting a layer of water soluble film and placing a walled open template on the film, filling the template with a wood preservative grease and removing the template, placing a porous layer of material over the grease and lacing a layer of protective film over the porous material and forming a seam between the outer layers around the grease.

Accordingly, an object of the present invention is to provide an improved wood preservative grease bandage for mounting on an applicator to apply to the top of a line pole.

A further object of the invention is to provide an improved wood treatment bandage of simplified construction well adapted for use in the field for protecting the grease product, and for ease of opening and attachment to an applicator and adapted for convenient handling and application to the top of a line pole.

A further object of the invention is to provide an improved method and mechanism for manufacturing bandages of the type described, wherein the bandages can be quickly and easily made without contact by the operator with the preservative grease product. I

A still further object of the invention is to provide an improved wood treatment bandage construction and package therefor for storing and handling.

An overall object of the invention is an improvement in the art of applying a material to the top of standing 3,181,696 Patented May 4, 1965 poles and to poles prior to installation which will provide long term weather protection as well as a wood preservative treatment, and relates to an improvement in the application of the material and to the form in which it is produced, packaged, handled and applied.

An object is to produce a satisfactory bandage which accommodates the varying shapes and sizes of the tops of poles, the sticky and very solvent nature of such compounds which give satisfactory preservation and protection, and which provides an end product that is sate and attractive.

Other objects and advantages will become more apparent with the teaching of the principles of the invention in connection with the disclosure of the preferred embodiments thereof in the specification, claims and drawings, in which:

As shown on the drawings:

As illustrated in FIGURES 1, 2 and 4, the bandage 14 has a first support film 15 of water soluble material. For example a two mil thick polyvinyl alcohol cold water soluble film is well suited. On the support film 15 is paced a circular slab or deposit of wood preservative grease 16 such as a pentachlorophenol based grease. A preservative-protective material such as that described in U.S. Patent 2,904,467 Behr, is well suited.

Over the grease 16 is placed a layer of porous material 17 such as crinoline. The layer acts as a separator permitting easy separation and removal of an upper protective film 18 which is later cut from the bandage along the line 20 and the center portion stripped off so that the grease preservative product 16 can penetnate the crinoline 17 and penetrate the pole top to which it is applied. The crinoline is shown as a rectangular patch in FIGURE 1, extending past the grease 16 at its ends. This permits an applicator to clamp the ends of the crinoline, FIGURE 4, and hold the pad of grease in position. The protective layer of film 18 is preferably of the same composition as the support layer 15, being of a water soluble film, so that its edges, which are left on the bandage when the center of the film 18 is removed, will dissolve when exposed to weather and precipitation. The lower and upper layers 15 and 18 of film are joined a layer although it can extend over its-edges. V a V His flaws- '9??? thef'greaseafterthetemplate by a continuous seam 19 and the film is preferably a I thermoplastic material so'that a heat seal can be used.

This will provide a closedpackage preventing bleeding out ut the grease or the escape of odors andjfu mes For use and application to the top of a pole, the'protective' layer 18 is'cut such as by a knife or razor blade along the line indicated-at 20,50 that thecenterportion canbe shipped on to expose: the crinoline layer. The. bandage isthen appliedto a pole top, and may be handled by an applicator such as shown in FIGURE 4 having" a is raised, the possibility of the layer 44 being lifted with the template is avoided.

FIGURES 8 and 9 show a machine for performing the method and making the package of the invention, including a table 45 with a support table top 46.

When the slabs have been'deposited by filling in the open: ings 50 in the template49, the template is pivoted-up wardly torthe position of FIGURE 9, patches of crinoline are placed over each of the slabs of grease, and an upper layer is drawn from the roll 48 -0ver the slabs. Heat seals are formed surrounding each of the slabs by sliding heat sealed bars 52 and 53. The bar 52 is slidablyfm'ounted on .a rail 51 at ens side of the table so as to move alongand form cross seals between the slabs. Similarly, the bar 54 is slidable on a rail 53 on an adjacent side outwardly thereof. The seams are forrned in double rows as indicated schematically in FIGURE 8 by the seam-lines 52a and 54a and the material is cut between the seam lines to complete the packages. 7

FIGURES 10 and 11 and FIGURE 12 illustrate ways in which the bandage is packaged for shipping, with FIG- URE l2 illustrating an advantageous way of shipping multiple bandages. In FIGURES 10 and 11, a bandage 56 is placed in acontainer'55 which may be of fiberboard or a similarmaterial and may be circular inshape or rectanbandage may be square,
